[Photo/Xinhua] HARBIN - The relay satellite for the Chang'e 4 lunar probe, which is expected to land on the far side of the Moon later this year, has been named Queqiao - magpie bridge. The name was announced by the China National Space Administration (CNSA)Tuesday, China's Space Day. In a Chinese folktale, magpies form a bridge with their wings on the seventh night of the seventh month of the lunar calendar to enable Zhi Nu, the seventh daughter of the Goddess of Heaven, to cross and meet her beloved husband, separated from her by the Milky Way. Together with the relay satellite, two microsatellites, developed by the Harbin Institute of Technology, will also be sent into orbit. The two microsatellites were named Longjiang 1 and Longjiang 2. Work on the Chang'e 4 lunar probe is progressing well, said Li Guoping, a spokesman of CNSA. Chang'e 4 will carry payloads for Germany, the Netherlands, Saudi Arabia and Sweden, The far side of the mood is of great scientific interest, but landing there requires a relay satellite to transmit signals. The relay satellite will be sent into the halo orbit of the Earth-Moon Lagrange Point L2 in late May, and the Chang'e 4 lunar lander and rover will be sent to the Aitken Basin of the south pole region of the Moon about six months later. 1 inch wide silicone wristbandsbracelets for a causecustom name bar braceletpersonalized heart braceletrubber bracelets
The newest members of China's military arsenal are a host of laser weapons, as the country makes a serious commitment to cutting-edge hardware.China Aerospace Science and Industry Corp, the nation's largest missile maker, has developed a road-mobile laser defense system called the LW-30, which the company is promoting to international markets.The LW-30 uses a high-energy laser beam to destroy targets ranging from drones and guided bombs to mortar shells. It features high efficiency, rapid response, a good hit rate and flexibility, according to CASIC.An LW-30 combat unit is composed of one radar-equipped vehicle for communications and control on the battlefield, at least one laser gun-carrying vehicle and one logistical support vehicle.The laser gun can be deployed with close-in weapons systems and air-defense missiles to form a defensive network free of blind spots, the company said.It said that in a typical scenario, the LW-30's radar will scan, detect and track an incoming target before transmitting the information to the laser gun. The gun will analyze the most vulnerable part of the target and then direct a laser beam onto it. Destruction takes place in a matter of seconds.Fast-moving targets such as guided bombs and mortar shells are difficult to intercept with most types of existing weapons because they are too fast to be caught and usually come in large quantities, said Wu Peixin, an observer of advanced weaponry in Beijing, adding that while advanced air-defense missiles are capable of hitting such targets, it is unreasonable to use an expensive missile to bring down a bomb or shell."Therefore, a laser gun is the most suitable weapon to defend against these threats," he said. "Every military power in the world has been striving to develop laser weapons. They have bright prospects in the international arms market."In addition to CASIC, other State-owned defense conglomerates are ready to take their laser weapon systems to market.China Shipbuilding Industry Corp, the world's largest shipbuilder, has made another vehicle-mounted laser weapon that integrates detection and control devices and the laser gun in one six-wheeled vehicle. Observers said the system should be fielded to deal with low-flying targets such as small unmanned aircraft.China South Industries Group, a major manufacturer of ground weapons for the military, is trying to attract buyers for its mine-clearing laser gun, which is carried by a light-duty armored vehicle. Designers said the system is able to dispose of land mines from a distance, avoiding hazards to personnel.
